Forms Don't Load After Upgrading To .NET Framework 4.0
Mar 10, 2012
I have upgraded a solution with several projects inside from VS2005 to VS2010, and because of a dependency issue I updated all projects to target .NET Framework 4.0. One of the VB projects now doesn't load two of its forms. I got an error:
[Code].....
Another form loads perfectly. The DependentVBProject builds fine, and is set as a dependency for the startup project.
Before upgrading to .NET Framework 4.0, this project loaded fine, but something else that had it as a dependency did not build (because of other 4.0 dependency).

I have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

In Entity Framework (specifically EF 3.5, but if it exists in EF 4 it gives me a reason to upgrade) is it possible to lazy load only part of a collection? I may be approaching this wrong too, so I'm open to suggestions. My tables/entities look similar to this:
[Code]...
The issue is this is loading up the entire collection. Granted it's a small collection so worst case scenario I can load it all up and then remove all but the one I need, but that is far from ideal. Plus I'm not sure if it would be possible without triggering any of the events of modifying the collection since they shouldn't have been in there in the first place.

1. Does Windows load the .Net framework at boot time? How can I check (eg. some DLL running in the background)? How much RAM does the framework use, so that I check I have enough to pre-load at boot time? Once loaded, will it stay in RAM?
2. What is the point of JIT once the application is installed on a given computer? Are there drawbacks about compiling into binary code applications that I use often on my own computer so that no time is wasted recompiling the application every time it's ran? If not, can I compile apps for which I only the .Net bytecode?
3. Is the framework downward-compatible, ie. will a 2.0 application run if I only have the 4.0 framework installed?

Is it possible to load a referenced assembly only if the .NET Framework version is lesser than a specific number? I'm using a selfmade LINQ library on .NET 2.0, but if the framework is 3.5+, it should use the M$ LINQ library, and ignore the selfmade one.
Here's my library: [URL]

If I look at some classes in the framework, using reflector, I can see that forms and user controls are made private and nested into a parent class.For instance, I have a control which makes use of pop-up form that is specific to that control.At the moment, I make the pop-up form friend accessible.If I wanted to do it the framework way, I'd make it private and nest it into the control class.If I do this, however, I can no longer use the ide to design the form and I get errors when I try to compile.

I have been tasked with upgrading a large web application from .net 1.1 to 3.5. I have converted it using Visual Studio 2008, and it compiles ok. Should I be expecting everything to work correctly straight off? And if not can anyone suggest what are the major pitfalls I should be looking out for. Should I be taking the time to write and carry out a full test for the entire system, or is that overkill?

We are upgrading a VB6 project to VB.NET. I ran it though an upgrade utility (Artinsoft). I guess the question is where is the GUI. In VB6, there is a form designe and Object mode. That does not exist in vb.net correct???
It looks like during the upgrade the entire GUI, the forms, the buttons, they are all gone. None of that was upgraded. So does the entire GUI have to be recreated in asp.net or something?

I m using this code:
Imports Transactions 'Transaction is my projects name from which I want to call forms
In Button Click Event
Dim FrmDrVouchers As Transaction.FrmDebitVouchers = New Transactions.FrmDebitVouchers()

When I click the customer service button, it mistakenly loads that form and teh hiring form with it. When I click the hiring button, it only loads the hiring button. That is teh only thing the program gets right. The employee button won't function for some odd reason. What am I doing wrong. I was trying to use if statements to open the individual forms one at a time, and in the process try to avoid error messages. My vb6 code was

I am new to Visual Basic (I currently have VB 2008 Express to play with) and have a question about automating MS Access applications.I have a number of MS access applications that interact with MS Excel, Windows commands and Adobe writer.The applications have multiple forms that require input and/or selection from dropdown list which are repeated for 15 different selections manually.Rather than change the application can I write something in VB to perform the manual process of filling foelds and clicking buttons? e.g. I can open a DB, display a form and then this requires two fields to have a date input, then a new form loads and a dropdown is selected. This is used to generate a report.I can see how to run the report and load forms, but can/how do I update the fields in the form.

I have this code which is working fine;
Private Function GetForm(ByVal frmName As String, ByVal asm As Assembly) As Form
Dim types As Type()
Dim t As Type
types = asm.GetTypes
Dim frm As Form
[Code]...
if you will notice, the sub still needs to scan all forms before it display the form, please help to reconstruct the code so that I will not use the "for next" for in types, since assembly and formname are already given/provided.

I am developing a windows app in VS2008 to be used along side ESRI�s ArcMap. Most ArcMap users will have dual monitors and I would like the user to be able to choose which monitor my app is loaded on to.
When I deploy the app using the standard install package, the app will load onto which ever monitor the user places the desktop shortcut. However, when using the ClickOnce method of deployment, the placement of the shortcut does not matter and the app always loads on the primary display monitor.
Is there a way to control where an app is loaded by code or any other method?

I got a combobox, that when the texted is changed, its supposed to run a query to update a field in my database. Here is the issue The event im using is TextChanged, well unfortunately when the page loads, it changes the text when populating the values. Is there a way to make this event wait to fire until after the list is populated? Ive ran into this problem before with datetimepickers, but I was able to offset it with a boolean, but this combobox is calling the textchanged event everytime it adds an item to the list.

I had created a form(MDI Child) which have 3 to 4 dataset on it. They all are loaded from the database at the form load event and therefore takes too much time to load and show some part of form during that time. When it load completely it shows the whole form. Is there any way that user will see the complete form instead of some broken form.

so what I want to do should be pretty simple. I've been following the examples found here Using the BackgroundWorker Component - VBForums . I've been successful, but I'm not smart enough to put it in my project.
What I'd like to happen is this
1. I hit a button to load data from a dataset....
2. have a progress bar show until this action is complete.
The main problem is that I can't figure out how to tie the "progress bar" to the action of "pulling the dataset"
I'm sure this is a crazy question for you all, but hey...
Would I put all of the coding in the button_Click sub?

Hi,
How to load multiple SAME forms location? I have no problem to load 2 different forms' location but the multiple same forms' locations.
The following code is for loading the different forms:
Private Sub Menu_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Location = My.Settings.Location
Me.Visible = True
'Usually i have multiple Form1 are opened when i close app.
Dim f1 As New Form1
f1.Location = My.Settings.test
f1.Visible = True
End Sub
Thank you for the helps!

I am performing a migration on a vb6 program, to vb.net. The basic knowledge you need to understand this question is that there are two forms that need to talk to each other, frmInput1 and frmInput2. I have the following code (behind frmInput1) that checks if a textbox on frmInput2 has a certain value, seemingly before it has loaded:
